Séropositivité VIH dans les dons de sang : prévalence, risque résiduel et épidémiologie

Abstract

As it has been observed since the beginning of anti-HIV screening in blood donations, the rate of seropositive donations has been still decreasing during these 4 last years: 0.090/1000 in 1991 to 0.042/1000 in 1994. This decrease has been observed in blood donations from first-time donors (0.38 to 0.17/1000) and from regular donors (0.060 to 0.030/1000). However, the residual risk from cellular components, such as it is estimated, seems to be stable. The proportion of blood donations positive for both anti-HIV and anti-HBc was constantly decreasing from year to year: 63% between 1985 and 1988 and 25% in 1994. The repartition of seropositive donors into sex, ages and at-risk groups during this recent period was the same as previously observed.
